My suggestion is to return the textbook first, and don't think the examples are simple. The questions in the senior high school entrance examination are all variants of those questions. If you do it seriously, the effect is obvious!

I don't suggest doing all of them, but doing them selectively. Now, don't lose face. Go directly to the teacher and ask him to draw you valuable questions. After all, you know the exam trends ~ ~

Just choose "essential", which is clear and simple, and has no digression.

Also, don't just do the questions. It is also important to answer the rebate. By the way, you should also learn other problem-solving methods.

Finally, I hope you succeed in the senior high school entrance examination. Your own efforts are very important! ! Come on! And happy new year, pay attention to reasonable study and entertainment! ~~
